Unfortunately, in my experience, building libpalo_ng requires you to update the Jedox build files which are a bit outdated. I've made some notes on how to do this below, but you don't come right, then let me know and I'll build an RPM for fedora 18 using koji for you. If you opt to go the pre-build RPM route you'll need to let me know which architecture you using 32-bit or 64-bit intel or ARM.

There are 3 topics which we need to address:
1. the build process relies on boost, but ships with an old version to the boost macro. In my experience this needs to be updated. You can get the updated macro here: raw.githubusercontent.com/tsun…master/build-aux/boost.m4
This file needs to replace ax_boost.m4 in ~/libpalo_ng/source/m4/ax_boost.m4
A simple copy and paste of the updated version from Firefox into gedit should work.

2. The file confgure.ac is now old and on newer versions of Fedora results in an error. The following changes are required in ~/libpalo_ng/source/configure.ac: After the line:
AC_PROG_INSTALL
Delete the line:
AC_PROG_LIBTOOL
And then add the following line in the same location:
LT_INIT
Again you should be able to make this change using gedit or similar.

3. The the build process itself needs to back-track a bit to re-generate some of the intermediate files that appear to have been generated on an older version of Debian. In particular, the following sequence works for me:
cd ~/libpalo_ng
sudo yum install libtool
sudo yum install icu
sudo yum install libicu-devel
sudo yum install boost-devel
sudo yum install openssl-devel
autoreconf
#The next command assumes you using 64-bit fedora. If you using 32-bit, then drop the 64 i.e. just /usr/lib
./configure --disable-static --libdir=/usr/lib64
make
sudo make install

4. The libpalo_ng.so files should now be in /usr/lib64.

I've been meaning to create an PRM for the palo php client for a while, but not being a PHP user myself, am a bit unsure of how to check if it works. If you've got some spare time, I'd appreciate you input.
